This means, that we need to make sure that a font is at least subset embedded when we create and distribute PDF documents, otherwise somebody who does not have that particular font will not be able to view or print the document the way the author created it. The font foundry licensed the font to the author of the document with the right to embed it in the document so that you (without a valid license) can still view and print the document, but you cannot modify the document. If the only copy of the font you have is the copy that is embedded in the PDF document, you do not have a licensed to use the font. This is done to comply with font licenses: You can only use the font (and editing a document would require you to use the font) if you have a license for the font. Otherwise you cannot edit the text set it that font. It is not sufficient to have the font embedded in the document, it needs to be installed on the computer. The question that usually comes up at this point is вЂњThat all sounds very good, but doesnвЂ™t subset embedding mean that I cannot edit this document with the TouchUp Text tool (or the вЂњEdit Text & Images tool in Acrobat XI) if the whole font is not embedded? If I only have вЂSвЂ™ and вЂOвЂ™ embedded, but I need to change the title to вЂњS.O.S.вЂќ, I would not have access to the period.вЂќДЄcrobat actually requires that the font for text that you edit in Acrobat is available as a system font. Given this list of different options, it should be clear that the subset embedding method is the best way to use a font in a PDF document: The font will always be there when needed, but we are also not wasting any space by adding the complete font when we donвЂ™t need it.

There is no need to embed any other glyphs, so you end up with the smalls possible PDF file. In this case, you can embed only the glyphs for вЂњSвЂќ and вЂњOвЂќ and you can render this title. LetвЂ™s say you have a book titled вЂњSOSвЂќ вЂ“ the title is set in a font that is not used anywhere else in the book.

This is very similar to an embedded font, but in this case, only those вЂњglyphsвЂќ (these are the вЂњdrawingsвЂќ of a character that appear in your PDF viewer, or on a printed page) that are actually used in the file (or on a certain page) are embedded. Also, in the case where you only need a few characters that are set in a certain font, the whole font would have to be embedded. fonts for Asian languages), that would expand the file size dramatically. The drawback of this approach is that some fonts are huge (e.g.

This means, the font вЂњtravelsвЂќ with the PDF file and is always available when the file is being displayed or printer.

A PDF file can have the font embedded in the file.

How exactly this situation gets handled depends on what software you are using to process the PDF file, and if itвЂ™s a viewer, or a PDF printer. In this case, the PDF document will only contain a reference to a font, and if that font is not available, it will either be substituted or the PDF document cannot be processed. A PDF file can rely on the correct font being available on the target computer or printer.
